I’ve had an issue with slicing a particular model in Snapmaker Orca for printing on a U1. I painted the entire object with filament “2”, which is just black PLA in my current setup. When I slice the object, I noticed that it shows filament “1” (pink PLA in my setup) in the list of filaments, along with a filament change times of 5. After looking around, I found that it made one little blip of pink filament right in the middle of the print for some reason. I’ve been digging through settings, re-created and re-painted the project in snorca several times, and it keeps doing similar things on this model. I don’t believe I’ve had any other models do this, or maybe I just didn’t notice it. It’s not a huge deal on this print, but it’s odd and I’d like to figure out how to stop it.
Has anyone seen anything like that? I’ve used Orca for years without much issue, but this is my first mutli-filament printer so this is a new one to me.
If you have a 3MF file, you can submit a ticket and send it to the technical staff for analysis. Or you can post it here for everyone to analyze together.
You can submit a ticket at the same time in case the technical staff or fellow users in the forum don’t respond promptly.
I forgot to mention, I did find one way to fix it for this specific print. Under Multi-material, I changed all of the “filaments for features” settings to filament 2, re-sliced it, and that little blip of filmanent 1 is gone now. However, it seems like setting a specific filament for walls would cause issues if I were actually trying to do a multi-filament print.
From my perspective, it should be an issue with the model. You might have exported some extra points, lines, or faces or there might be some abnormal broken faces in the model when exporting.
That may be me not understanding the best way to do this in orca. I have used orca for quite a while, but never with multi-filament printers, so this is all a bit new to me. When I bring in an STL, it imports it all as whatever filament is in head 1 in the U1 - pink PLA in my case. What I had been doing was just opening the painter tool and painting the entire object with whatever filament head I wanted to actually print it. So in this example I used the color painting tool, select filament 2, use the fill tool with edge detection turned off, and paint the entire object. That is the process that produced the model with the little blip of filament 1 in it. I have used this same process to make quite a lot of other single filament prints without any issue.
At least for this model, if I go in to the multimaterial tab in orca and set the walls, infill, and solid infill all to filament 2, then that resolved the issue.
I guess I have two questions. Is either of those the most “correct” way to do that in this case, or is there a better way? And then how does whichever process is best change or what effect does that have on multi-filament prints?
Instead of painting, set the majority (or single color) of the model by selecting the part then press the number of filament that corresponds to the color you want, 1, 2, 3 or 4.
Or you can use the drop-down menu to select the color on the part.
It’s best not to paint to change the color ofa single part print, or to set the majority color of the part.
If the print has separate parts, use this same method to change the color of complete parts.
